If you have tried to play Cave Story+ on a Mac before, you know that that version is beyond broken.
In fact, after apple dropped support for 32-bit apps, it became unplayable.

Yeah that's the thing that irritates me the most. On Nicalis's website, ( https://www.nicalis.com/games/cavestory+ ) they use screenshots from the Switch version, but list Switch and Steam as equal platforms, even though the Steam version is inferior.
